You're getting some very good advice thus far. Serious RVing is sort of an acquired taste and it's not for everybody. As mentioned, it's not a real cost saver and you have an older teenager and young daughter with needs/desires that make a somewhat nomadic life potentially very difficult if not impossible.
I like the idea of taking a good vacation break, and concentrate more on establishing a stable and liveable lifestyle potentially somewhere else if your current situation dictates that and then down the road oncee reestablished and happy, reinvestigate getting more into the RV side of things.
